SPECIFICATION forming part of Letters Patent No. 308,726, dated December2 1884-.

Application filed January 31, 1884. (N0 model.)

To aZZ whom it may concern:

Be it known that I, JAMES J. ADAMSON, a citizen of the United States ofAmerica, residing at Olney, in the county of Richland and State ofIllinois, have invented certain new and useful Improvements in CombinedPulverizer and Grain-Drill; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and toletters or figures of reference marked thereon, which form a part ofthis specification.

My invention has relation to combined planters and ground-levelers; andit consists in the improved construction and combination of partshereinafter described and set forth.

In the accompanying drawings, forming part of this specification, Figurel is aperspective view of a machine constructed in accordance with myinvention. and Fig. 3 is a section on the line 3 3 Fig. 2.

A B are respectively bars constituting the frame of the machine. Atongue, 0, is centrally secured to the front bar, A, and is braced bysuitable rods, a, and carries a suitable drafttree, I). A hopper, D, issuitably supported on the frame by means of standards a. Thecarrying-wheels E turn on the end of an axle, F, which is bent up andin, so as to be journa-led in bearing d, secured upon the upper side ofthe bars B. The axle is then bent vertically to extend up above thecover 6 of the seed-box, and the said vertical portions are unitedtransversely by a horizontal bar, f. A vertical spring-standard formedby the bent rod g, secured at its ends to the frame at one side of thesame, is adapted to normally bear against one of the vertical portionsofthe axle and maintain the same in the position shown in Fig. 1. Acylinder or cylinders, G, are rigidly secured to a shaft, H, by a seriesof spiders, h, the, ends of the shaft H turning in bearings t, formed onthe under side of the bars B. The shaft H has rigidly secured to it, ateach side of its bearings, a series of disks, j, which prevent lateraldisplacement of said shaft in its bearings. The cylinder or cylin- 5oders G have projecting from them at various Fig. 2 is aninverted plan,

points a series of crescent blades, is Z. As shown in Figs. 2 and 3, theblades is are arranged diametrically opposite each other, and do notextend more than a fourth the circumference of the said cylinder orcylinders. The blades [are arranged so as to alternate with the blades76, and are located at points on the circumference of the cylinderbetween the blades 75. A series of fingers, m, project from the rear barA into and between the blades Z, so as to remove dirt clinging to saidblades. One end of the cylinder-shaft H carries rigidly a smallband-pulley, n, which, by the motion it derives from the revolution ofthe cylinder, drives by a belt, 0, a second pulley, 10, rigidly securedon the end of the hopper-valve shaft q. A curved plate or guard, I,issecured at the front of the machine between the hopper D and frame,and prevents any dirt being thrown by the cylinder upon the clothes ofthe attendant, whose feet rest on the fender J. By disengaging the axlefrom the springstandard 9 and moving the rod 6 so as to turn thevertical portions of the shaft to ahorizontal position, thereby throwingup the crank extremities of the shaft rearwardly and elevating thecarrying-wheels E, the weight of the machine is thrown upon the cylinderor cylinders, causing the blades of one transverse series to cut intothe ground, while the draft on the machine results in the revolution ofthe cylinder and the successive all of the blades.

By arranging the blades 70 Z as herein described the necessity for acontinuous blade is dispensed with, the resistance of the blades greatlyreduced, and all the ground within the transverse area of the machinesubjected to the pnlverizing action of the blades and the levelingaction of the cylinder or cylinders. Furthermore, the crescent shape ofthe blades enables them to more readily and gradually enter the ground.
